Ellesmere Port

Cambi is supplying two thermal hydrolysis process (THP) systems to the Ellesmere Port bioresources treatment centre in Cheshire, supporting United Utilities’ AMP8 programme to modernise sludge treatment and expand renewable energy generation.

The project is delivered in partnership with J. Murphy and Sons Limited as part of United Utilities’ Enterprise delivery model.

United Utilities is transitioning to centralised sludge treatment across north-west England, consolidating operations into fewer, modern facilities. This approach reduces methane emissions, improves efficiency, and supports compliance with the Industrial Emissions Directive.

At Ellesmere Port, thermal hydrolysis will enable the site to accept sludge from a wider catchment. Around two-thirds of the facility’s planned throughput will be imported from other locations, strengthening its role as a regional hub.

United Utilities serves more than seven million people and thousands of businesses across north-west England. The Ellesmere Port site is also being upgraded to accommodate population growth and increased industrial loads, including flows linked to the Stanlow refinery.

The addition of thermal hydrolysis supports both capacity expansion and more sustainable sludge management.

The Ellesmere Port project builds on Cambi’s longstanding relationship with United Utilities and forms part of a wider investment programme to modernise bioresources infrastructure across the region.

Equipment delivery is scheduled for late 2027, with operations starting in 2028.
